초록

본 논문에서는 인셋 급전 구조에서 마이크로스트립 패치 안테나 소형화를 위해 접지면에 CSLR 9개 적용한 안테나('CSLR 09' 안테나)와 8개 적용한 안테나('CSLR 08' 안테나)를 설계한 후, 유전율 2.5, 두께 0.787 mm인 기판으로 안테나를 제작하여 반사손실과 복사패턴에 대한 이론 결과와 실험 결과를 비교하였다. 'CSLR 09'와 'CSLR 08' 안테나의 이론 결과에서는 공진주파수 2.82 GHz에 반사손실이 각각 -25.35 dB와 -16.77 dB를 보였고, 측정결과에서는 공진주파수 2.885 GHz에 반사손실이 각각 -30.72 dB와 -14.90 dB를 나타내어 두 경우 모두에서 거의 일치하는 결과를 얻었다. 또한 E-면과 H-면 복사패턴에 대한 실험 결과에서도 이론 결과와 거의 일치하는 양호한 결과를 얻었다.

In this paper, design and fabrication for inset fed microstrip patch antennas applied to the $3{\times}3$ array CSLR and eight CSLR, respectively, to the ground plane are studied. The theoretical results are compared to the experimental results for the return loss and radiation pattern. For 'CSLR 09' antenna, the theoretical result for the resonant frequency and the return loss are 2.82 GHz and - 25.35 dB, respectively. The experimental results are obtained for a 2.885 GHz, -30.72 dB. Theoretical results for the resonant frequency and the return loss of the 'CSLR 08' antenna are 2.82 GHz, -16.77 dB, respectively, and the experimental results are obtained for a 2.885 GHz, -14.90 dB. In addition, E-plane and H-plane radiation patterns in comparison with designed and fabricated antennas are in good agreement.
